More and more portable devices now use ceramic capacitors for filtering of dc/dc-converter inputs. Ceramic capacitors offer the advantages of small size, low ESR (equivalent series resistance) and ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...

Many analog signal-chain circuits require ac-coupling to eliminate unwanted dc voltages or offsets. The simplest means to ac-couple is to use a capacitor in series with the signal path, thus forming a ...

For EMI filtering and noise attenuation, California-based Johanson Dielectrics is offering a range of novel multi-layer ceramic devices that combines two balanced shunt capacitors with mutual ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...

Full-wave rectifiers with capacitor filters are, without question, the workhorse — and the unsung hero — of the modern electronic world and for the gadgets we have come to enjoy. That being said, it ...

A research team led by Prof. MENG Guowen from the Institute Solid State Physics, Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS), cooperating with Prof. WEI Bingqing ...

In the 1960s, mainframe computers took up entire rooms. By the 1980s, there were individual workstations and just a few decades later, laptops and smartphones became ubiquitous. Today’s technology is ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...
